"(I Wanna) Testify" is the first hit single by the Detroit soul singing group The Parliaments. The single was released at the beginning of the summer of 1967 by Revilot Records. The single went to #3 on Billboard R&B chart and #20 on the Pop chart. It would be the only major hit for the group for the entire decade. The only member of the Parliaments to actually appear on the recording was group leader George Clinton, as the group was based in New Jersey at the time and only Clinton was able to travel to Detroit for the session. The recording was rounded off by session singers and musicians.

"(I Wanna) Testify" was reissued in 1969 on the Soultown label (Soultown 502-A). It was issued in Canada on the Transworld label (TW-1677) and on the Track label (Track 604032) in the UK. The first time that the single appeared on an album was the Track Records release Backtrack 6 in 1970 (Track 2407 006).

Group leader George Clinton later produced remakes of both "(I Wanna) Testify" and its B-side "I Can Feel The Ice Melting". The former appeared on the 1974 Parliament album Up For The Down Stroke under the abbreviated title "Testify". "I Can Feel The Ice Melting" was re-done by Otis Day and the Knights in 1989. Another P-Funk spin-off act, the Brides Of Funkenstein recorded a version of "I Can Feel The Ice Melting" in 1978, but the track wasn't released until the 1993 archival release "A Fifth Of Funk". That recording was produced by P-Funk production assistant Ron Dunbar.
